Question

The following substances are put into the blast furnace when manufacturing iron: coke, ore, limestone, and hot air.

Write the equation for the reduction reaction which produces iron.

Answer 1

• Haematite or Iron(III) oxide when reacts with Carbon monoxide, Haematite is reduced to iron, and Carbon dioxide is formed.
• The chemical equation involving the reduction reaction for the making of iron is written below-
• $\underset{\left(\mathrm{Haematite}\right)}{{\mathrm{Fe}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)}+\underset{(\mathrm{Carbon}\mathrm{monoxide})}{3\mathrm{CO}\left(\mathrm{g}\right)}\stackrel{∆}{\to }\underset{\left(\mathrm{Iron}\right)}{2\mathrm{Fe}\left(\mathrm{l}\right)}+\underset{(\mathrm{Cabon}\mathrm{dioxide})}{3{\mathrm{CO}}_2\left(\mathrm{g}\right)}$
• Here, Carbon monoxide($\mathrm{CO}$) acts as a reducing agent.
